Pics taken during May 26 and processed in June. The most fun about this image was it was the first time I used an OSC camera to also take Ha images. The result was that the reds in the image had greater emphasis thus making a more interesting image. Ya, I finally figured out how to do that with PI.
ASI585MC Pro g200, AskarV@600f7.5, 75 10min pics (12.5 hours) exposure,
+darks/biases/flats + Ha 36 10min pics (6 hours) exposure
AM5/ASIair+, EAF, Askar OAG with ASI174mini for guiding
PixInsight 100%.
After linear processing was complete the RGB(OSC) image was blended with the Ha image using PI. The resulting image was then processed using typical methods to complete the final image.
